i ROTARY MOTOR.

Specification of Letters Patent.

Application filed September 13, 1907.

Patented July 14, 1908.

Serial No. 392,640.

To all whom 'it may concern:

Be it known that I, ARTHUR WHTTE, residing in Sheboygan Falls, in the county of Sheboygan and State of Wisconsin, have invented new and useful Improvements in Pressure-Expansion Rotary Motors, of which the following is a description, reference being had to the accompanying drawings, which are a part of thisspecication.

This invention relates to improvements in pressure expansion rotary motors.

One of the objects contemplated is to provide a motor having a rotary member withina casin and adapted to receive steam under full boi er pressure at the periphery of the rotating member and to'exhaust the same at the center.

Another object is to provide a motor with an inlet passageway extending entirely around the rotary member, so that in starting the motor, steam being admitted to the 1plassageway will cause the same to expand rst, thereby preventing binding between the casing and the rotary member.

A further object of this invention is to form the casing into a lurality of parts adjustably connected toget er to provide means for making a very iine adjustment between the workin arts.

A st' l urther object of this invention is to provide pockets and passageways so positioned and shaped that after the steam has imparted all of its energy to therotary member it will be free to exhaust through the exhaust opening at the center.

With the above and other'incidental objects in view, theinvention consists of the motor and arts, or their equivalents, as hereinafter escribed.

4o Like numerals of references refer to corresponding parts throughout the different views of the drawings.

In the accompanying drawings, Figure 1 is a front view of the motor, the casing and shaft being in section and the rotary member having a part broken away therefrom; Fig. 2 is a vertical section of the motor taken on line 2-2 of Fig. 1; Fig. 3 is a vertical section of the main ortion of the motor casing, the rotary mem er being removed therefrom anda portion of the inner surface being broken away to show one of the passageways; Fig. 4 is a plan view of the rotar member and a portion of the connected s aft; Fig. 5 is a plan view of a fragment of the rotary member ona large scale, parts broken away and in seetion and Fig. 6 is a cross section of a frage ment of the rotary member showing the passages between the peripheral pocket and the side pockets.

In the drawings the reference numeral 8 indicates a cylindrical shaped member provided with a base portion 9 integral therewith and forming the main portion of the casing, the base portion serving as a support for the motor. The inner portion of the cylindrical shaped member is partially threaded and has connected thereto by means of said threads, face plates 10, 10, the face plates being correspondingly threaded. The face plates 10, 10 7o have centrally outwardly projecting portions provided with adjustable bearings 11, 11 threaded thereto and held in adjusted osition by means of am nuts 12, 12. fournaled in the adjustablebearings 11, 11 and 75 surrounded by packing glands 13, 13 is a shaft 14 which is partially tapered upon both sides of a rotary member'15 rigidly connected thereto and positioned within the cylindrical shaped member and between the face lates. The adjustable bearings are provide with tapered o enings corresponding to the taper of the sha t journaled therein, and are adapted to adjust the position of the rotary member 15 with relation to the face plates. 85

The shaft 14 is provided with a pulley 16 for belted connection and application of the power of said motor. The peri hery of the rotary member is tapered and t e inner surface ofthe cylindrical member is also tapered coincident therewith providing means of adjustment between the rotary member and the cylindrical member.

The cylindrical member 8 is provided with an inlet passageway 17 extending entirely 95 around the cylindrical portion of the casing 8 and has' connected thereto a steam feed pipe 18 connected to a source of supply such as a boiler (not shown) and serving to supply steam under full boiler pressure to said passageway. A series of inlet ports 19, 19 lead inwardly and tangentially in the direction of rotation of the rotary member, and are so positioned in order to direct the jets of steam or fluid under pressure tangentially into the curved pockets 20, 20 coincident therewith and extending almost entirely across the periphery of therotary member 15 -to rotate the same. Passageways 21, 21 connect the curved pockets 20, 20 to angular side pockets 110 22, 22 and are adapted t0y deflect the fluid in the opposite direction by the angularity of said side pockets. Outer pockets 23, 23 in the face plates 10, 10 register radially with the pockets 22, 22 in the rotary member 15. Curved passageways 24, 24 connect the side pockets 23, 23 with inner pockets 25, 25 located closer to-the shaft 14. Inner pockets 26, 26 in the rotary member 15 are adapted to register with pockets 25, 25 and also with exhaust pockets 27, 27, which are connected to the tubular portion 2S of the shaft 111.

The pockets 27, 27 are connected together by means of an annular recess 29 to provide a free exhaust from all of the pockets, and to still further enlarge the exhaust passages, annular recesses 30, 30 coincident with the annular recesses of the faceplates, are formed in both sides of the rotary member, and radial recesses lead from the annular recesses to the hollow portion of the shaft.

The inlet passageway 17 is provided with a series of six sets of inlet ports 19, 19 and the face plates are likewise provided with a series of six sets of pockets and six exhaust pockets so that fluid under pressure passes from the inlet ports 17 to the exhaust ports 26 in substantially one-third of a revolution of the rotary member. It is obvious, however, that the motor may have any number of series of inlet and outlet ports without departing from the spirit and scope of the invention. The number of pockets may also be changed radially, without departing from the invention.

The inlet passageway 17 is reduced in size near its closed end as it is only necessary to provide a capacity sufficientlylarge to supply the one series of inlet ports located at this point.

Lugsl 31, 31 bolted to the cylindrical shaped member are provided with set screws 32, 32 and are adapted to firmly hold the face plates in adjusted positions with relation to the cylindrical shaped member.

Discharge passages 33, 33 are located at the lowermost portions of the chamber within the cylindrical shaped member to discharge water of condensation which may accumulate therein, and sight gages 34 provided with pet coclrs35 are connected to the passages to control the discharge of the said water of condensation. Oil cups 36, 36 are connected to the face plates and are adapted to lubricate the inner portions of the shaft and the rotary member.

ln adjusting the parts after being assembled, the rotary member is ositioned so that its tapered periphery will freely turn but remain steam tight with the inner tapered surface of the cylindrical shaped member. The face plates are then turned by means of their threaded engagement with the cylindrical shaped member until the inner surfaces of the face plates just touch the outer faces of the rotary member. The face plates are then locked in position by means of jam nuts 12 and the set screws 32. An adjustment of the rotary member with relation to the face plates may be made by means of the threaded bearings 11, 11, and the tapered portions of the shaft.

In operation steam or fluid under pressure is admitted to the inlet passageway extel'lding around the cylindrical portion of the casing and passing through the tangential ports in jets forcibly acts upon the wall of the curved pockets in the periphery of the rotary member and causes the rotation of said rotary member. The steam or l'luid under pressure will now begin to act by expansion and in expanding will pass through the passageways connecting the curved pockets to the angular side pockets and ejected from the latter pockets in the 0ppm site direction against the walls of the pockets in the face plates and by expansion and reaction add further impetus to the rotating rotary member. The fluid under lessened pressure will continue to expand and will pass through the curved passageways and will again be deflected in the opposite direction and ejected from thc inner ports against the walls of the inner )oclrets of the rotary member and add stil further impetus to the rotary member. 'lhe fluid in the inner pockets of the rotary member will be carried by said member un til said pockets successively come into register with the exhaust pockets in the face plates when each pocket will eject the contained fluid and in ejecting will receive reactionary effect therefrom but in a less degree than formerly described due to the reduced pressure of the fluid. The fluid is now free to pass from the exhaust pockets into the tubular portion of the shaft and be discharged into the atmosphere from the open end thereof.

From the foregoing description it will be seen that a motor is provided which is constructed to receive the full boiler pressure at the periphery of its rotary member where it has the greatest power and leverage, and it is then allowed to impart its remaining energy by expansion as it is successively passed through deflecting passageways and expansion pockets and is finally discharged at the center of the rotary member, the point of least effective back pressure. Provision is also made for making very line adjustment in assembling the parts and also to compensate for wear.

Another object in applying equal pressure simultaneously around the periphery of the rotary member is to lessen the friction hetween the shaft and the bearings.

It is obvious that the exhaust opening may be disposed adjacent to the axis of rotation instead of-at the axis, without departing from the spirit and scope of the invention.
